ARM: dts: keystone-k2g-evm: fix rgmii phy-mode for ksz9031 phy
Since commit
bcf3440c6dd7 ("net: phy: micrel: add phy-mode support for the
KSZ9031 PHY") the networking is broken on keystone-k2g-evm board.
The above board have phy-mode = "rgmii-id" and it is worked before because
KSZ9031 PHY started with default RGMII internal delays configuration (TX
off, RX on 1.2 ns) and MAC provided TX delay by default.
After above commit, the KSZ9031 PHY starts handling phy mode properly and
enables both RX and TX delays, as result networking is become broken.
Fix it by switching to phy-mode = "rgmii-rxid" to reflect previous
behavior.

As it turns out, mxc_register_gpio() is a bit lax when setting the
number of resources: it registers a resource with interrupt 0 when in
reality there is no such interrupt. Fix the problem by not declaring
the second interrupt resource if there is no second interrupt.

mips: Remove compiler check in unroll macro
CONFIG_CC_IS_GCC is undefined when Clang is used, which breaks the build
(see our Travis link below).
Clang 8 was chosen as a minimum version for this check because there
were some improvements around __builtin_constant_p in that release. In
reality, MIPS was not even buildable until clang 9 so that check was not
technically necessary. Just remove all compiler checks and just assume

mlxsw: pci: Fix use-after-free in case of failed devlink reload
In case devlink reload failed, it is possible to trigger a
use-after-free when querying the kernel for device info via 'devlink dev
info' [1].
This happens because as part of the reload error path the PCI command
interface is de-initialized and its mailboxes are freed. When the
devlink '->info_get()' callback is invoked the device is queried via the
command interface and the freed mailboxes are accessed.
Fix this by initializing the command interface once during probe and not
during every reload.
This is consistent with the other bus used by mlxsw (i.e., 'mlxsw_i2c')
and also allows user space to query the running firmware version (for
example) from the device after a failed reload.

====================
net: macb: Wake-on-Lan magic packet fixes and GEM handling
Here is a split series to fix WoL magic-packet on the current macb driver. Only
fixes in this one based on current net/master.
Changes in v5:
- Addressed the error code returned by phylink_ethtool_set_wol() as suggested
by Russell.
If PHY handles WoL, MAC doesn't stay in the way.
- Removed Florian's tag on 3/5 because of the above changes.
- Correct the "Fixes" tag on 1/5.
Changes in v4:
- Pure bug fix series for 'net'. GEM addition and MACB update removed: will be
sent later.
Changes in v3:
- Revert some of the v2 changes done in macb_resume(). Now the resume function
supports in-depth re-configuration of the controller in order to deal with
deeper sleep states. Basically as it was before changes introduced by this
series
- Tested for non-regression with our deeper Power Management mode which cuts
power to the controller completely
Changes in v2:
- Add patch 4/7 ("net: macb: fix macb_suspend() by removing call to netif_carrier_off()")
needed for keeping phy state consistent
- Add patch 5/7 ("net: macb: fix call to pm_runtime in the suspend/resume functions") that prevent
putting the macb in runtime pm suspend mode when WoL is used
- Collect review tags on 3 first patches from Florian: Thanks!
- Review of macb_resume() function
- Addition of pm_wakeup_event() in both MACB and GEM WoL IRQ handlers

net: macb: fix macb_get/set_wol() when moving to phylink
Keep previous function goals and integrate phylink actions to them.
phylink_ethtool_get_wol() is not enough to figure out if Ethernet driver
supports Wake-on-Lan.
Initialization of "supported" and "wolopts" members is done in phylink
function, no need to keep them in calling function.
phylink_ethtool_set_wol() return value is considered and determines
if the MAC has to handle WoL or not. The case where the PHY doesn't
implement WoL leads to the MAC configuring it to provide this feature.

net: macb: mark device wake capable when "magic-packet" property present
Change the way the "magic-packet" DT property is handled in the
macb_probe() function, matching DT binding documentation.
Now we mark the device as "wakeup capable" instead of calling the
device_init_wakeup() function that would enable the wakeup source.
For Ethernet WoL, enabling the wakeup_source is done by
using ethtool and associated macb_set_wol() function that
already calls device_set_wakeup_enable() for this purpose.
That would reduce power consumption by cutting more clocks if
"magic-packet" property is set but WoL is not configured by ethtool.

net: macb: fix wakeup test in runtime suspend/resume routines
Use the proper struct device pointer to check if the wakeup flag
and wakeup source are positioned.
Use the one passed by function call which is equivalent to
&bp->dev->dev.parent.
It's preventing the trigger of a spurious interrupt in case the
Wake-on-Lan feature is used.

io_uring: account user memory freed when exit has been queued
We currently account the memory after the exit work has been run, but
that leaves a gap where a process has closed its ring and until the
memory has been accounted as freed. If the memlocked ulimit is
borderline, then that can introduce spurious setup errors returning
-ENOMEM because the free work hasn't been run yet.
Account this as freed when we close the ring, as not to expose a tiny
gap where setting up a new ring can fail.

KVM: nVMX: fixes for preemption timer migration
Commit
850448f35aaf ("KVM: nVMX: Fix VMX preemption timer migration",
2020-06-01) accidentally broke nVMX live migration from older version
by changing the userspace ABI. Restore it and, while at it, ensure

according to the KVM_STATE_VMX_PREEMPTION_TIMER_DEADLINE flag.

net/mlx5e: Fix port buffers cell size value
Device unit for port buffers size, xoff_threshold and xon_threshold is
cells. Fix a bug in driver where cell unit size was hard-coded to
128 bytes. This hard-coded value is buggy, as it is wrong for some hardware
versions.
Driver to read cell size from SBCAM register and translate bytes to cell
units accordingly.
In order to fix the bug, this patch exposes SBCAM (Shared buffer
capabilities mask) layout and defines.
If SBCAM.cap_cell_size is valid, use it for all bytes to cells
calculations. If not valid, fallback to 128.
Cell size do not change on the fly per device. Instead of issuing SBCAM
access reg command every time such translation is needed, cache it in
mlx5e_dcbx as part of mlx5e_dcbnl_initialize(). Pass dcbx.port_buff_cell_sz
as a param to every function that needs bytes to cells translation.

net/mlx5: Fix eeprom support for SFP module
Fix eeprom SFP query support by setting i2c_addr, offset and page number
correctly. Unlike QSFP modules, SFP eeprom params are as follow:
- i2c_addr is 0x50 for offset 0 - 255 and 0x51 for offset 256 - 511.
- Page number is always zero.
- Page offset is always relative to zero.
As part of eeprom query, query the module ID (SFP / QSFP*) via helper
function to set the params accordingly.
In addition, change mlx5_qsfp_eeprom_page() input type to be u16 to avoid
unnecessary casting.

Restore gcc check in mips asm/unroll.h
While raising the gcc version requirement to 4.9, the compile-time check
in the unroll macro was accidentally changed from being used on gcc and
clang to being used on clang only.
Restore the gcc check, changing it from "gcc >= 4.7" to "all gcc".
[ We should probably remove this all entirely: if we remove the check
for CLANG, then the check for GCC can go away. Older versions of clang
are not really appropriate or supported for kernel builds - Linus ]

kbuild: Move -Wtype-limits to W=2
-Wtype-limits is included in -Wextra which is added at W=1. It warns
(among other things) that 'comparison of an unsigned variable `< 0` is
always false. This causes noisy warnings, especially when used in
macros, hence it is more suitable for W=2.
